Third charged over NSW road rage incident

A third person has been charged over an ugly road rage incident that saw a man punch a woman in the face while stopped in traffic on the NSW Central Coast.

Footage of the confrontation, captured by a nearby motorist, was uploaded to social media on Monday.

It showed a 41-year-old man approach the 21-year-old woman, who was standing next to a silver ute, before punching her in the head.

But the video didn't show the lead up to the violence, and police allege the woman had thrown objects at the man's car.

The man was charged with assault occasioning actual bodily harm, while the woman was later charged with offences including malicious damage, being armed with intent to commit and indictable offence, and intentionally throwing objects at a vehicle.

Police have now arrested a 23-year-old woman, alleged to be the driver of the silver ute.

She was charged with driving in a manner dangerous to the public, malicious damage, not complying with 'P' licence and driving with an unrestrained passenger.
